@ March 17, 2014 9:59 PM in Mercury control replacementI was introduced to ... The R powered a heater in the thermostat which you can change the disks to give you different cycles on the thermostat which was a big thing converting from coal to oil with huge radiators . The heat anticipator replace the disks, now we can just program ..
The RA117 before that was the Mercoide with mercury tubes which lasted forever but was loaded with brass and you can cash in on the mercury too back then and it was slow as Kansas ... Yes if the the motor clapper welded shut on the 117 you would loaded the boiler if you had a low voltage limit . . The ing clapper had to pull in first , the side points on the clapper made the motor clapper ... We use to replace the helix and clappers out in the field and clean the points with files and coat with #2 pencils
The first ones where three wire for the series 10 thermostats ... Those old heat sensor controls where so slow action and easy to throw out of step . Yes that old crap .
@ March 16, 2014 1:38 PM in Mercury control replacementI remember that control , the upper makes on temperature rise, it's a B for the circulator the other is the A for winter limit.. They were used in the era of the series 10 summer and winter control that was installed in the side arm , Can't remember the number , top lever hozontal control with a switching relay .....

@ March 7, 2014 9:00 AM in What brand of indirect hot water heater would one recommend ?I like the idea of stainless , but it's a tough metal to weld , that where the issues comes in with leaking stainless tanks ... Turbomax is a nice design with large copper coils where the water runs through ... I do not see too many or heard of any issues with them. What I understand with the correct boiler , circulator and proper size tank , you can size for an endless supply of hot water for your needs .... Which could be good or bad if you have daughters that hog the bathroom :)
@ March 7, 2014 8:42 AM in superstor or amtrolSize the tank to the biggest load , Either how much water to fill the tub or length of shower . Say tub size is 50 gallon your not going to fill to top ,40 gallon would work..To figure shower its GPM x time ....Say you have 2.5 GPH flow rate shower head and you take a 15 min shower , 2.5gphx15m= 37.5 gallon tank , To figure flow rate take a 5 gallon bucket open shower and time how many gallons in a min ...
@ March 6, 2014 5:43 PM in Back up boiler sizeWhen you find out what is needed through your heat loss calculation . You will find out the better smaller oil fire boilers come from Europe ... Like the Buderus G115 ... Well made , three pass, positive pressure boilers and there indirects are well made too ... Throw the outdoor reset on with the remote room sensor ... When the fire cools down the boiler would take over ...
